Thanks, Ray!
AFAIK civil twilight comes around 6am and the Sun rises about 6:20 at earliest. This means programs should be longer than 6 hours to pull start time forward to the preceding day. I know it is technically possible to create such a long program but is it a reality? My programs never exceeded 3 hours, if for nothing else but cost saving reasons.
I do hope you’ll find a solution to this. Me and my lawn would really appreciate it!
